To aZZ 'whom t may concern:

Be it known that I, JACOB HENRY HARD, a citizen of the United States, and a resident of Usmond, in the county of Pierce and State of Nebraska, have invented a new and Improved Tire-Deilating Cap, of which the following is a specilication.'

My invention is an improvement in tire intlating valves, andhas for its object the provision of two caps, one of which is provided with an internally threaded end of the same diameter as the cap, and the other cap is'externally threaded for engaging either the ring or the cap, and both caps are provided with pins extending centrallyfrom the inelosed end of the caps, and the pin of the inner cap is provided with a transverse notch.

ltn the drawings :Figure lis a side'view ont the improvement; Fig. 2 is a vertical section; F ig. 3 is a side View showing the parts reversed; and Fig. 4 is a bottom plan view oi F ig. 3. i

lin the present embodiment of the inven4 tion, a tube 1 is provided, having at its center a diaphragm 2. The tube is internally threaded on one side of the diaphragm, as indicated at 3, and is reduced externally at the said end, as indicated at 4, and an annular shoulder 5 is formed between the reduced portion and the main portion. The opposite end oi. the tube is reduced in diam` eter by otlsetting the end of the tube in- Wardly, asindicated at 6, and an annular series of openings 7 is provided in the wall oli' the tube between the diaphragm and the inwardly otliset portion. The otl'set portion 6 is threaded internally, as shown at 8 and externally as shown at 9. A pin 11 extends axially of the tube from the center of the diaphragm toward the offset end, and a packing plate l2 is arranged on the opposite face ot' the diaphragm. A second tube is composed oi' two portions 13 and 14 ol" unequal diameter connected by a tapering por- '1`he portion 14 is externally threaded at 16, and an annular radial rib 1S extends from the inner end of the portion 14 at the junction of the'portions 14 and 15. '.lhe rib is adapted for engagement by the end of the oitset portion of the tube, and the lsaid rib is provided with a lateral flange 19,

extending parallel with the surface of the tube, and extending over the end of the offset' portion of the tube, When the end of the said portion engages the rib. The outer end of the ortion 3 is longitudinally slotted or notche at 20. The internal diameter of the portion 6 of the tube l is the same as that ot t portion 4 of the'oth' tube and the portion 14 will t in either end of the tube 1. The device presents in fact two tubes so ar ranged that eitherend of one will screw upon a valve stem, one end rotecting the valve in the usual manner, an the other end opening the valve by means of its in for the escape of air, and so arranged t at one end of the smaller will screw into either end of the larger tube Where it may be'carried in order to be used as a wrench lfor the removal of the valve core.

[The oset. portion 6,`when the parts are in the position of Figs. 1 and 2, engages outside of the portion 14 of the tube .1B-4.4, to assist in holding the parts in their position and to prevent the easy disengagement 'of the tube 13--14 from the cap 4. The portion 13-14 of the device has a double engagement with the deflating cap, since the portion 14 screws into the portion 6 and the portion 19 ts outside of the said portion. The flange 19 is made short, so that the greater part of the thread of the portion 14 will be exposed, a ortion sufficient to enter the portion 4 of tie other section. Vhen' yusing the device as a deilater, the tube 13l4,which is merely the wrench for removing the valve from the valve stern,v

might be slightly set in, and the Vsaid tube might be lost while the device is being used to deflate..

I claim: l As an article of manufacture, a deiating device comprising a cap and an integral coaxial ring, said cap being internally threaded and the ring being internally and exter nally threaded and of the saine internal diameter as the cap, the cap havingapin coaxial with the ring, and a second cap externally threaded for engaging Within the first named cap or within the ring, said second cap having a tubular stem provided with a transverse notch at its free end and having a radially outwardl offset flange for engaging outside of t e outer threaded surface of thev ring, for the purpose specified.
